A lot of good advice from TRB especially. Here's a few extra/complementary thoughts that may help you.
To expand on the better mouse-trap cliche a little with another well-worn adage: marketing is about making what you can sell
not selling what you can make. This is very important and explains many a failed business enterprise quite succinctly.
In other words, you may need to radically change how you present yourself and your offerings and think laterally in order to monetize your skills most effectively. It's no good saying 'this what I do, please buy it'. As TRB said, if the market's not there you won't sell a thing. I have had many a prickly conversation with my clients over the years on this very topic!
That's why the first thing I would do in your shoes is to really get to know the similar businesses online who are doing what you do, but doing it very successfully. Know your competitors inside out. Understand what they do and why they do it.
Subscribe to their YT channels, visit their websites regularly, follow on instagram and Facebook and Twitter, even buy their lessons. Then see how they use the various conversion techniques (via email in particular in this market seemingly) to convert their subscribers and followers to paying customers. Then nick all their techniques.
In the recording sector you'll see people making money from advertising on YT, selling courses, templates, samples etc. A good example of the sharp ones that I consider to be doing it right is The Recording Revolution. https://www.youtube.com/user/recordingrevolution
He has a good website, really good YT presence, sends informative and useful emails. He uses classic marketing techniques, too, behind his cheery exterior...stuff like long-copy squeeze pages (Google these if you don't know what they are) to convince you to buy, limited time offers, discounts (sorry, you HAVE to offer discounts).
Another one might be Rick Beato who seems to have grown his subscribers very rapidly or, for a UK one on a slightly different topic, Justin Guitar. I was trying to isolate what the successful ones have in common and it's, amongst other things:
* A fairly distinct niche: eg Recording Revolution is very much aimed at the beginner
* A very cheery and TV-friendly personality on video. This is SOOOO vital on YT. Certainly more important than your CV.
* A constant stream of useful, relevant and helpful content. Or simply entertaining content to drive subs. New YT videos every week, new posts on their website/blog every week.
*A constant stream of emails, at least weekly, driving you to YT or website etc
* High production values in their videos and on the website
* A catchphrase or visual gimmick that adds to their distinctiveness
*All their marketing activities interact with each other, constantly looping visitors around from YT, to website, to emails, to facebook, to YT, to website etc etc
*They understand how to put together YT vids to get found, with the right sort of content, presentation, titling and so on. There are endless vids and web pages on how to do this. But again, look at the successful folk and you'll see they all do very similar things
*They have a constant friendly dialogue with YT followers and blog subscribers, they come across as your mate who's happy to help so you feel you have a real 1 to 1 relationship with them.
